Demonstrators protest in front of the Federal Supreme Court of Brazil against the Supreme Court decision to allow a retrial on charges for which defendants received at least four votes for acquittal, in Brasilia September 18, 2013. Brazil's top court voted narrowly on Wednesday to allow retrials in the country's biggest-ever political corruption case, a decision seen by many as a major setback for efforts to hold Brazilian officials accountable for wrongdoing. The ruling could save Jose Dirceu, the political leader in the so-called "mensalao" or monthly payment scandal, from going to prison.
